"General Motors claimed a new world record for EV driving on a single charge," reports the Verge, "after a Chevy Silverado EV traveled 1,059.2 miles without recharging its battery." The potentially record-breaking run took place over seven days on public roads near GM's Milford Proving Ground and Detroit's Belle Isle "using smart driving techniques" that included limiting the speed to 20-25 mph. The truck was a 2026 Chevy Silverado EV Work Truck with an EPA-estimated range of 493 miles. But by making a number of adjustments, GM's engineers were able to far surpass the vehicle's estimated range...

First of all, the test was conducted in the summer for "optimum ambient temperature for battery efficiency," GM says. They also lowered the windshield wiper blades to reduce drag, inflated the tires to the highest acceptable pressure for lower rolling resistance, removed the spare tire to lighten the load, and optimized the wheel alignment. A tonneau cover was added to the truck bed for smoother airflow, and climate control was turned off for the duration of the test.
GM isn't seeking the Guinness World Records, the article adds, with a GM spokesperson calling it "a passion project led and executed by GM engineers." (The test "started out as casual conversation among a group of GM engineers in late 2024," GM says, but "quickly turned into a challenge: How far could the Work Truck go if we optimized absolutely everything?")

After the test, reports Motor Trend, "The dead truck was hauled back to Milford, its battery was topped up, and the energy used to power a Stratasys F370 3D printer, which spent 6.5 hours printing an ABS plastic trophy to commemorate the auspicious event."

Ancient Slashdot reader Epeeist shares a report from The Guardian: The newest version of the maglev train is capable of traveling at 600km/h (about 370mph). However, the train's engineers have wrestled with the problem of the shock waves which occur as the train exits the mouth of a tunnel. When a high-speed train enters an enclosed space such as a tunnel, air in front is compressed, like in a piston. The resulting fluctuations in air pressure coalesce at the tunnel mouth, generating low-frequency shock waves. These are colloquially known as a "tunnel boom" -- a related, albeit different phenomenon to the "sonic boom" heard as aircraft pass the speed of sound. Tunnel booms pose serious challenges to operational safety, as the shock waves can disturb humans and animals nearby, as well as causing structural damage.

Now, however, researchers have discovered that placing innovative soundproofing buffers at tunnel mouths can reduce shock waves by up to 96%. This promises improvements in operational safety, noise pollution and passenger comfort, as well as safeguarding animals in the vicinity of future lines. [...] The porous structure of the new 100-meter long buffers, combined with porous coatings on the tunnel body, allow the trapped air to escape before the train reaches the tunnel mouth, suppressing the boom in the same way as a silencer fitted to a firearm.

An anonymous reader quotes a report from the New York Times: China's automakers have teamed up with software companies togo global with their driverless cars, which are poised to claim a big share of a growing market as Western manufacturers are still preparing to compete. The industry in China is expanding despite tariffs imposed last year by the European Union on electric cars, and despite some worries in Europe about the security implications of relying on Chinese suppliers. Baidu, one of China's biggest software companies, said on Monday that it would supply Lyft, an American ride-hailing service, with self-driving cars assembled by Jiangling Motors of China (source paywalled; alternative source). Lyft is expected to begin operating them next year in Germany and Britain, subject to regulatory approval, the companies said.

The announcement comes three months after Uber and Momenta, a Chinese autonomous driving company, announced their own plans to begin offering self-driving cars in an unspecified European city early next year. Momenta will soon provide assisted driving technology to the Chinese company IM Motors for its cars sold in Britain. While Momenta has not specified the model that Uber will be using, it has already signaled it will choose a Chinese model. In China, "the pace of development and the pressure to deliver at scale push companies to improve quickly," said Gerhard Steiger, the chairman of Momenta Europe. China's state-controlled banking system has been lending money at low interest rates to the country's electric car industry in a bid for global leadership. [...]

Expanding robotaxi services to new cities, not to mention new countries, is not easy. While the individual cars do not have drivers, they typically require one controller for every several cars to handle difficulties and answer questions from users. And the cars often need to be specially programmed for traffic conditions unique to each city. Lyft and Baidu nonetheless said that they had plans for "the fleet scaling to thousands of vehicles across Europe in the following years."

The U.S. Transportation Department is proposing new rules to speed deployment of drones beyond the visual line of sight of operators, a key change needed to advance commercial uses like package deliveries. From a report: "We are going to unleash American drone dominance," Transportation Secretary Sean Duffy said at a press conference on Tuesday.

Under current rules, operators need to get individual waivers or exemptions to use drones without visual line of sight. The department said eliminating those requirements "will significantly expand the use-case for drone technologies in areas like: manufacturing, farming, energy production, filmmaking, and the movement of products including lifesaving medications."

The proposal includes new requirements for manufacturers, operators, and drone traffic-management services to keep drones safely separated from other drones and airplanes. "It's going to change the way that people and products move throughout our airspace... so you may change the way you get your Amazon package, you may get a Starbucks cup of coffee from a drone," Duffy said.

An anonymous reader quotes a report from Politico: Transportation Secretary Sean Duffy will announce expedited plans this week to build a nuclear reactor on the moon, the first major action by the former Fox News host as the interim NASA administrator. NASA has discussed building a reactor on the lunar surface, but this would set a more definitive timeline -- according to documents obtained by POLITICO -- and come just as the agency faces a massive budget cut. [...] The reactor directive orders the agency to solicit industry proposals for a 100 kilowatt nuclear reactor to launch by 2030, a key consideration for astronauts' return to the lunar surface. NASA previously funded research into a 40 kilowatt reactor for use on the moon, with plans to have a reactor ready for launch by the early 2030s.

The first country to have a reactor could "declare a keep-out zone which would significantly inhibit the United States," the directive states, a sign of the agency's concern about a joint project China and Russia have launched. The directive also orders NASA to designate a leader for the effort and to get industry input within 60 days. The agency is seeking companies able to launch a reactor by 2030 since that's around the time China intends to land its first astronaut on the moon. The nuclear initiative means that NASA will continue to have a hand in nuclear development even after the Pentagon's recent cancellation of a joint program on nuclear-powered rocket engines. "While the budget did not prioritize nuclear propulsion, that wasn't because nuclear propulsion is seen as a non-worthy technology," the NASA official said.

Rivian has filed a federal lawsuit in Ohio to challenge a state law preventing it from selling electric vehicles directly to consumers, arguing the rule is anti-competitive and outdated. The law currently protects legacy dealerships while allowing Tesla a special carve-out, and Rivian wants similar rights to apply for a direct-sales license in the state. TechCrunch reports: "Ohio's prohibition of Rivian's direct-sales-only business model is irrational in the extreme: it reduces competition, decreases consumer choice, and drives up consumer costs and inconvenience -- all of which harm consumers -- with literally no countervailing benefit," lawyers for the company wrote in the complaint. Rivian is asking the court to allow the company to apply for a dealership license so it can sell vehicles directly. Ohio customers have to buy from Rivian vehicles from locations in other states where direct sales are allowed. The cars are then shipped to Rivian service centers within Ohio.

Allowing Rivian to sell directly would not be treading new legal ground, the company argues in its complaint. Tesla has had a license to sell in Ohio since 2013 and can sell directly to consumers. What's stopping Rivian is a 2014 law passed by the state's legislature. That law, which Rivian says came after an intense lobbying effort by the Ohio Automobile Dealers Association (OADA), effectively gave Tesla a carve-out and blocked any future manufacturers from acquiring the necessary dealership licenses. "Consumer choice is a bedrock principle of America's economy. Ohio's archaic prohibition against the direct-sales of vehicles is unconstitutional, irrational, and harms Ohioans by reducing competition and choice and driving up costs and inconvenience," Mike Callahan, Rivian's chief administrative officer, said in a statement.

"Hyundai sold 79,543 vehicles in the U.S. last month," reports the EV news site Electrek — Hyundai's best July ever, and 15% higher than last year.

"The growth was mainly driven by electrified vehicles, including EVs and hybrids..." Hyundai said that electrified vehicle sales "reached new heights," after climbing 50% compared to July 2024. Electrified vehicles accounted for nearly a third (32%) of Hyundai's retail sales in July 2025, with several popular nameplates setting new all-time monthly sales records, including the new IONIQ 5.

Hyundai IONIQ 5 sales surged 71% in July with 5,818 units sold. Through the first seven months of 2025, Hyundai has now sold nearly 25,000 IONIQ 5 models in the US. Hyundai's electric SUV remains one of the top-selling EVs in the US, boasting a long driving range, ultra-fast charging capabilities, advanced technology, and a stylish design. After upgrading it for the 2025 model year, the IONIQ 5 now features a range of up to 318 miles, an upgraded infotainment system, and a built-in NACS port, allowing you to charge at Tesla Superchargers... Hyundai is also offering a complimentary ChargePoint L2 home EV charger with the purchase or lease of a new 2025 IONIQ 5 or 2026 IONIQ 9.

The vehicle "once led the Space Shuttle down the runway at Edwards Air Force Base," The Drive reported in 2022, noting it was won in an auction for $21,061 (beating 18 other bidders). "I just figured the NASA brand combined with Airsteam hip seemed like a can't lose combination," the buyer says now, in a listing for the vehicle on the on the automotive sales site Hemmings.com asking $199,000..

They're touting it as a priceless marketing/publicity prop — "a once in a lifetime opportunity" to own what was once an "onsite command center complete with communications and atmospheric monitoring... Imagine pulling into Burning Man driving this..." The seller points out it's the only custom-built "Airstream" trailer ever sold by NASA. (The others were crushed, except for one donated to the Kennedy museum.) But for this one "Apparently there was some miscommunication when the vehicle was decommissioned. It should have been offered to museums but the sales team did not know what it was.")

"Has only 8240 miles on it as driven from Ohio to California then around the Edwards base."

The seller apparently first tried listing it on eBay in May for $50,000. ("Reserve not met," says that listing page now. "Very well maintained, minor dings on exterior...")

Aurora Innovation has expanded its autonomous trucking operations with nighttime driverless runs between Dallas and Houston and a new Phoenix terminal. "Efficiency, uptime, and reliability are important for our customers, and Aurora is showing we can deliver," said Chris Urmson, co-founder and CEO of Aurora, in a press release. "Just three months after launch, we're running driverless operations day and night and we've expanded our terminal network to Phoenix. Our rapid progress is beginning to unlock the full value of self-driving trucks for our customers, which has the potential to transform the trillion-dollar trucking industry." FreightWaves reports: The expansion allows for continuous utilization, shortening delivery times and serving as part of its path to autonomous trucking profitability. Aurora notes that the unlocking of nighttime autonomous operations can also improve road safety. It cited a 2021 Federal Motor Carrier Safety Administration report on large truck and bus crashes that noted a disproportionate 37% of fatal crashes involving large trucks occurred at night. This comes despite trucks traveling fewer miles during those hours.

Aurora's SAE L4 autonomous driving system, called the Aurora Driver, can detect objects in the dark more than 450 meters away via its proprietary, long-range FirstLight Lidar. The lidar can identify pedestrians, vehicles, and debris up to 11 seconds sooner than a traditional driver, according to the company. In addition to the fleet and operations expansion, the new terminal in Phoenix, which opened in June, is part of an infrastructure-light approach. Aurora notes this design will closely resemble how the company plans to integrate with future customer endpoints, optimized for speed to market.

This expansion of the more than 15-hour Fort Worth to Phoenix route opens up opportunities to showcase the autonomous truck's ability to cut transit time in half compared to a single driver, who is limited to the 11-hour hours-of-service limitation. Aurora is piloting the autonomous trucking Phoenix lane with two customers, Hirschbach and Werner.

Longtime Slashdot reader Mr_Blank shares a report from Autoblog: Once a new OTA update becomes available, owners of GM vehicles have 45 days to install the update. After this date, the company will not cover any damages or issues that are caused by ignoring the update. "Damage resulting from failure to install over-the-air software updates is not covered," states the warranty booklet for 2025 and 2026 models.

This same rule applies to all GM's brands in the USA: Chevrolet, Buick, Cadillac, and GMC. However, if the software update itself causes any component damage, that will be covered by the warranty. Owners coming from older GM vehicles will have to adapt as the company continues to implement its Global B electronic architecture on newer models, which relies heavily on OTA updates. Similar policies appear in the owner's manual for Tesla. Software-defined vehicles are here to stay, even if some of them have far more tech glitches than they should -- just ask Volvo.

Elon Musk's Boring Company plans to build a 10-mile underground transportation loop in Nashville connecting the airport to downtown, with private funding and a projected launch as early as fall 2026. "If that happens, Nashville would become the second city where The Boring Company has opened such a system, with the first being Las Vegas," notes TechCrunch. "The company has spent the last few years in Sin City digging and opening tunnels around the Las Vegas Convention Center, and claims to have given 3 million rides in Teslas to date." From the report: The project will be privately funded by The Boring Company "and its private partners," according to the Governor's press release, though those partners are not named. The Boring Company and local officials will now begin a "public process to evaluate potential routes, engage community stakeholders, and finalize plans for the project's initial 10-mile phase." Construction won't begin until the project clears the approvals process. But the governor's office said the first segment of the loop could be operational as "early as fall of 2026."

An anonymous reader shares an analysis: In most major aviation markets, including the U.S. and Europe, competition is an oligopolistic affair, with several large airlines competing for market share. India's domestic sector, however, is increasingly characterized by the ascent of a single airline.

Low-cost carrier IndiGo has achieved an extraordinary concentration of the market, capturing approximately 64.4% of all passenger traffic as of May. More strikingly, the airline operates with a near-monopoly on 66% of its domestic routes, facing little to no direct competition in a significant portion of its network.

This position is the culmination of a decade-long expansion that saw the exit of rivals like Jet Airways and GoAir. Today, its remaining competitors continue to struggle; SpiceJet's domestic market share has fallen to just 2% while it operates a reduced fleet of only 19 aircraft. Air India, despite its acquisition by the Tata Group in 2022, has been slow in its restructuring and continues to cede domestic ground, with the flag carrier remaining unprofitable.

The Airbus A380, the world's largest commercial passenger jet, faces mounting maintenance challenges as regulatory authorities issue an increasing number of safety directives. The European Union Aviation Safety Agency has listed 95 airworthiness directives for the A380 since January 2020, approximately double the number issued for large Boeing aircraft during the same period.

The directives address problems including leaking escape slides, cracked seals, and a ruptured landing-gear axle. A comprehensive maintenance check of the massive plane requires 60,000 hours of labor, according to aircraft repairer Lufthansa Technik. Airlines remain committed to operating the twin-deck aircraft due to limited large-capacity alternatives, with Boeing's 777X years behind schedule and Airbus unable to produce long-haul A350s quickly enough. British Airways plans to overhaul A380 cabins starting next year, while Emirates intends to keep flying the aircraft until the end of the next decade.

Tesla open its first diner/Supercharger station Monday in Los Angeles, reports CNBC — an always-open two-story restaurant serving "classic American comfort food" next to 80-charging stalls surrounded by two 66-foot megascreens "playing a rotation of short films, feature-length movies and Tesla videos."

Tesla described the restaurant's theme as "retro-futuristic". (Tesla's humanoid robot Optimus was outside filling bags of popcorn.) There's souvenier cups, the diner's food comes in Cybertruck-shaped boxes, and the owner of a Tesla Model Y told CNBC "It feels kind of like Disneyland, but for adults — or Tesla owners." (And yes, one of the choices is a "Tesla Burger.")

"Less than 24 hours after opening, the line at the Tesla Diner stretched down the block," notes CNBC's video report. (One customer told CNBC they'd waited for 90 minutes to get their order — but "If you're a Tesla owner, and you order from your car ahead of time, you don't have to wait in line.")

The report adds that Elon Musk "says if the diner goes well, he's looking to put them in major cities around the world."

American Airlines Chief Executive Robert Isom criticized the use of AI in setting air fares during an earnings call, calling the practice "inappropriate" and a "bait and switch" move that could trick travelers. Isom's comments target Delta Air Lines, which is testing AI to help set pricing on about 3% of its network today with plans to expand to 20% by year-end.

Delta maintains it is not using the technology to target customers with individualized offers based on personal information, stating all customers see identical fares across retail channels. US Senators Ruben Gallego, Richard Blumenthal, and Mark Warner have questioned Delta's AI pricing plans, citing data privacy concerns and potential fare increases. Southwest Airlines CEO Bob Jordan said his carrier also has no plans to use AI in revenue management or pricing decisions.

A new video shows flames emanating from one side of a Boeing 767 moments after takeoff, reports LiveMint.com. "Delta flight 446 was forced to make an emergency landing in Los Angeles," they report, adding "No one was injured. The fire was extinguished upon landing." According to a report by Aviation A2Z, the plane (24-year-old Boeing 767-400 with registration N836MH) had just departed from Los Angeles International Airport when its left engine ignited. The pilots promptly declared an emergency and requested to return to the airport.
Delta faced a similar issue less than three months ago. The article notes the engine of an Airbus also caught on fire in April when pushing back from the gate for departure. CBS News describes that incident: Delta said crew members evacuated the cabin when flames were seen in the tailpipe of one of the plane's two main engines and fire crews quickly responded. According to Delta, the plane, an Airbus 330, had 282 passengers, 10 flight attendants and two pilots on board...

The engine fire marks the latest aviation scare involving the airline in recent months. In February, 21 people were injured after a Delta plane flipped upside down while landing amid wintry conditions at Toronto Pearson International Airport. All of the injured passengers were later released from the hospital. In January, several people were injured after a Delta flight aborted its takeoff at Hartsfield-Jackson Atlanta International Airport, forcing about 200 passengers to evacuate the plane through emergency slides. ["A passenger says the engine on the Boeing 757 caught fire," according to CBS's video report in January.]

An anonymous reader shared this report from the Washington Post: Ships trigger seafloor methane emissions while moving through shallow water, researchers report in Communications Earth & Environment. The scientists say the unexpected discovery has nothing to do with the type of fuel used by the ship. Instead, "ship-induced pressure changes and turbulent mixing" trigger the release of the gas from the seafloor. Bubbles and gas diffusion push the methane into the atmosphere, where it acts as a greenhouse gas...

Container and cruise ships triggered the largest and most frequent methane emissions, but the study suggests that ships of all kinds, regardless of their type of engine or size, trigger methane emissions. Researchers said they observed emissions that were 20 times higher in the shipping lane than in undisturbed nearby areas. Given the number of ports in similarly shallow areas worldwide, it's important to learn more about emissions in shipping lanes and to better estimate their "hitherto unknown impact," study co-author Johan Mellqvist, a professor of optical remote sensing at Chalmers University of Technology in Sweden, said in a news release.

ABC News reports: Dialogue heard on a cockpit voice recording indicates that the captain of the Air India flight that crashed in June, killing 260 people, may have turned off the fuel just after takeoff, prompting the first officer to panic, according to The Wall Street Journal, which cited sources familiar with U.S. official's early assessment... The president of the Federation of Indian Pilots condemned the Wall Street Journal report, saying, "The preliminary report nowhere states that the pilots have moved the fuel control switches, and this has been corroborated by the CVR [cockpit voice recorder] recording."
But meanwhile "India on Monday ordered its airlines to examine fuel switches on several Boeing aircraft models," reports Reuters, "while South Korea ordered a similar measure on Tuesday, as scrutiny intensified of fuel switch locks at the centre of an investigation into a deadly Air India crash." The precautionary moves by the two countries and airlines in several others came despite the planemaker and the U.S. Federal Aviation Administration assuring airlines and regulators in recent days that the fuel switch locks on Boeing jets are safe... [The preliminary report] noted a 2018 advisory from the FAA, which recommended, but did not mandate, operators of several Boeing models, including the 787, to inspect the locking feature of fuel cutoff switches to ensure they could not be moved accidentally... Some airlines around the world told Reuters they had been checking relevant switches since 2018 in accordance with the FAA advisory, including Australia's Qantas Airways. Others said they had made additional or new checks since the release of the preliminary report into the Air India crash.
The web site of India's Financial Express newspaper spoke to Mary Schiavo, who was Inspector General of America's Transportation Department from 1990 to 1996 (and is also a long-time critic of the FAA). The site notes Schiavo "rejected the claims of human error that a pilot downed the Ahmedabad to London flight by cutting off the fuel supply." Schiavo exclusively told FinancialExpress.com that this is not the first time fuel switch transitioned from "Run" to "Cutoff" on its own. It happened five years ago, too. "There was an All Nippon Airways (ANA) flight in 2019 in which the 787 aircraft did this itself, while the flight was on final approach. No pilot input cutting off the fuel whatsoever," Schiavo told FinancialExpress.com... "The investigation revealed the plane software made the 787 think it was on the ground and the Thrust Control Malfunction Accommodation System cut the fuel to the engines," she told FinancialExpress.com, before adding, "The pilots never touched the fuel cutoff..." Both engines flamed out immediately after the pilot deployed the thrust reversers for landing. The aircraft, which was also a Boeing 787 Dreamliner, was towed away from the runway by the authorities, and no injuries were reported.

UK Civil Aviation Authority, four weeks before the crash, had warned about similar fuel system issues on Boeing aircraft [on May 15, 2025]. "The FAA has issued an Airworthiness Directive addressing a potential unsafe condition affecting fuel shutoff valves installed on Boeing aircraft," the UK regulator's notice read, listing the B737, B757, B767, B777 and B787...

Thrust Control Malfunction Accommodation informs FADEC [a digital computer] about whether the aircraft is on the ground or in the air, and if it believes the aircraft is on the ground, it may automatically throttle back the engines, without the pilot's input.
Reuters notes that the Air India crash preliminary report "said maintenance records showed that the throttle control module, which includes the fuel switches, was replaced in 2019 and 2023 on the plane involved in the crash."

Felix Baumgartner has died. He was 56.

In 2012 Slashdot extensively covered the skydiver's "leap from the edge of space." ABC News remembers it as a Red Bull-financed stunt that involved "diving 24 miles from the edge of space, in a plummet that reached a speed of more than 500 mph." Baumgartner recalled the legendary jump in the documentary, "Space Jump," and said, "I was the first human being outside of an aircraft breaking the speed of sound and the history books. Nobody remembers the second one...."

Baumgartner, also known as "Fearless Felix," accomplished many records in his career, including setting the world record for highest parachute jump atop the Petronas Towers in Malaysia, flying across the English Channel in a wingsuit in 2003, and base jumping from the 85-foot arm of the Christ the Redeemer statue in Brazil in 2007.
"Baumgartner's altitude record stood for two years," remembers the Los Angeles Times, "until Google executive Alan Eustace set new marks for the highest free-fall jump and greatest free-fall distance."

They report that Baumgartner died Thursday "while engaged in a far less intense activity, crashing into the side of a hotel swimming pool while paragliding in Porto Sant Elpidio, a town on central Italy's eastern coast." More details from the Associated Press: "It is a destiny that is very hard to comprehend for a man who has broke all kinds of records, who has been an icon of flight, and who traveled through space," Mayor Massimiliano Ciarpella told The Associated Press.Ciarpella said that Baumgartner had been in the area on vacation, and that investigators believed he may have fallen ill during the fatal flight... Baumgartner, a former Austrian military parachutist, made thousands of jumps from planes, bridges, skyscrapers and famed landmarks...
ABC News remembers that in 2022 Baumgartner wrote in Newsweek that "Since I was a little kid, I've always looked up to people who left a footprint on this planet... now I think I have left a footprint...

"I believe big dreamers always win."

An anonymous reader quotes a report from TechCrunch: California Forever announced on Thursday plans to build a massive manufacturing park called Solano Foundry, the newest addition to its master-planned "utopian" city backed by a group of Silicon Valley billionaires. Solano Foundry is 2,100 acres that can host 40 million square feet of advanced tech manufacturing space. The manufacturing park will be built as part of its planned walkable city with over 175,000 homes, CEO Jan Sramek said at the Reindustrialize conference in Detroit.

Sramek tweeted that U.S. manufacturers can't win by "building factories off of random freeway exits in the middle of nowhere. The best people don't want to work there." This site will offer expedited permitting, transportation for finished goods, and plenty of power from renewable energy, he said. The hope is that it will attract hardware, engineering, and AI talent from relatively nearby Silicon Valley. Solano County is about 40 miles northeast of San Francisco.
